We're dividing 84395679 by 456 
We want to figure out the number of times 84395679 can be divided by 456.

Going ahead to step 1:
8 divided by 456 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 456

Advancing to step 2:
When dividing 84 by 456, we get 0 with a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Include the next digit (3) from the dividend after 84, then repeat: 843 / 456

Step 3:
456 can be fit into 843 1 times, resulting in a remainder of 387.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 456 from 843 to get 387.
Take the next digit (9) from the dividend and append it to 387, then repeat: 3879 / 456

Advancing to step 4:
If we divide 3879 by 456, we get 8 and a remainder of 231.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 3648 from 3879 and we're left with 231.
Include the next digit (5) from the dividend after 231, then repeat: 2315 / 456

On to step 5:
When dividing 2315 by 456, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
If we take 2280 away from 2315, we end up with 35.
Bring next digit (6) of the dividend behind the 35 and repeat the process: 356 / 456

Step 6:
356 divided by 456 is 0 with a remainder of 356.
Put 0 as the next digit of the answer. 
Result so far: 1850.0
Deduct 0 from 356 and we're left with 356.
Append the next digit (7) from the dividend to 356 and continue with: 3567 / 456

Step 7:
456 can be fit into 3567 7 times, resulting in a remainder of 375.
Write down 7 as next digit of the result. 
Result so far: 18507.0
If we subtract 3192 from 3567, we get 375.
Append the next digit (9) from the dividend to 375 and continue with: 3759 / 456

Going ahead to step 8:
456 can be fit into 3759 8 times, resulting in a remainder of 111.
Write down 8 as next digit of the result. 
Result so far: 185078.0
The remainder is 111 after subtracting 3648 from 3759.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 9:
If we divide 1110 by 456, we get 2 and a remainder of 198.
Record the quotient 2 as the next digit in the result. 
Result so far: 185078.2
Deduct 912 from 1110 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 10:
If we divide 1980 by 456, we get 4 and a remainder of 156.
Write down 4 as next digit of the result. 
Result so far: 185078.24
If we take 1824 away from 1980, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 11:
456 goes into 1560 3 times with a remainder of 192.
Put 3 as the next digit of the answer. 
Result so far: 185078.243
Deduct 1368 from 1560 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 12:
1920 divided by 456 is 4 with a remainder of 96.
Record the quotient 4 as the next digit in the result. 
Result so far: 185078.2434
The remainder is 96 after subtracting 1824 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 13:
The number 456 fits into 960 2 times, leaving a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 185078.24342
If we subtract 912 from 960, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
The number 456 fits into 480 1 times, leaving a remainder of 24.
The next digit of our result is 1. 
Result so far: 185078.243421
Deduct 456 from 480 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 15:
240 divided by 456 is 0 with a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 185078.243421
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 16:
456 goes into 2400 5 times with a remainder of 120.
The number 5 becomes the next digit in our result. 
Result so far: 185078.24342105
The remainder is 120 after subtracting 2280 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 185078.24342105 with a remainder of 1.2e-07.
